Wireless power, light and automation control

What is this patent about?

’869 is related to the field of wireless home automation and power management. Specifically, it addresses the control of mains-powered appliances and lighting using standard mobile devices like smartphones and tablets. The background context involves the limitations of traditional Wi-Fi networks, which typically rely on a central wireless access point to route traffic between devices, creating a single point of failure and potential data latency issues.

The underlying idea behind ’869 is to eliminate the dependency on a central hub by establishing a direct, decentralized connection between the controller and the appliance. By leveraging peer-to-peer communication protocols, the invention allows a smartphone to act as a direct remote for power outlets and switches. This insight removes the need for a pre-existing network infrastructure, ensuring that the automation system remains functional even if a home router is disabled or overloaded.

The claims of ’869 focus on a power control device that initiates a connection by simulating a network access point. The independent claims specify a mechanism where the device always sends a discovery message to the mobile controller without passing through a router. This allows the power control unit to appear as a connectable network to legacy Wi-Fi devices or to negotiate a group owner role in a Wi-Fi Direct environment, effectively creating an ad-hoc, two-way communication link for power regulation.

In practice, the invention works by integrating a microprocessor and a wireless transceiver directly into a power housing, such as a wall plug or a light switch. When a user interacts with a dedicated application on their smartphone, the phone communicates directly with the unit to execute commands like switching power, dimming lights, or setting countdown timers. The device can also include power measurement circuits to monitor energy consumption and report real-time usage data back to the user interface.

This approach differs from prior solutions by bypassing the standard Wi-Fi architecture that requires all data to be bridged through an external router. Unlike proprietary systems like Zigbee that require specialized hardware, this invention utilizes the native Wi-Fi or Bluetooth capabilities already present in consumer smartphones. By simulating an access point, the device ensures compatibility with older hardware while providing the security and speed of a direct, local connection.
